[The EVA started at about 142:39:25 and, consequently, the elapsed time is about 6 hours 43 minutes. The Apollo 15 record was 7 hours 12 minutes. John and Charlie will get the record if they start cabin repress after about 149:52.]

[Although there is no mention of looking for Rover tracks on
the mountain, this is probably something Charlie was curious about before
the mission. The human eye can be a lot better than the Hasselblads in
picking out detail at a distance.]

[The UV camera has been taking data from a single
field-of-view - just above the summit of Stone Mountain - ever since John
last reset it at 143:23:03, just before he and Charlie started the drive to
Station 4.]

149:24:21 England: And, John, as you get off
the Rover, we'd like you to take a picture of the UV camera; it should be
about f/5.6 at 250.

149:24:36 Young: Roger.

149:24:40 England: You don't have to go up to it.

149:24:42 Young: From the Rover you want me to take that picture?

149:24:43 England: Yeah, just take it anywhere. As long as we can
see that location, that's all we're looking for.

[Fendell is looking toward the block-covered ridge SSW of the LM. He pans clockwise. John parked the Rover on a northeasterly heading at the MESA. If he has followed the procedures on CDR-21, his
heading is 351.]

149:24:56 Duke: TV Remote. (Hearing Tony) Okay.

149:25:03 Young: (Wondering if f/5.6 is the right Hasselblad setting) Actually, just the normal old thing ought to catch it, Houston; because it's not in Sun but there sure is a lot of Sun behind it and on it and all that. Very strange. It's in shadow.

[As shown in the camera decals in Figure 5.3-2 in the Lunar Surface Procedures volume, f/5.6 was normally used for up-Sun photos taken with either color (HCEX) or black-and-white (HBW) film.]

[Journal Contributor Markus Mehring notes "'HCEX' is a cryptic acronym for the Apollo standard color film emulsion, used both in the Hasselblads ('HCEX') and the 16-mm Maurer cameras ('CEX'). Its full name is 'Ektachrome MS Film, Type SO 368 (19 DIN, 64 ASA)', and amateur and professional photographers worldwide know it as 'Ektachrome X' - hence the 'EX'."]

[Fendell pans past Charlie, who may be dusting the front of the
Rover.]

149:25:20 England: Okay. I guess they wanted to see into the shadow
a little bit.

149:25:23 Young: (Garbled) that? (Stops to listen) Okay. Well, I
mean the leg...the shadows...You'll be able to see it fine.

[John takes three pictures of the UV Camera, AS16-114-
18468,
18469, and
18470. Neither he nor Charlie take any more pictures during this EVA.]

[Charlie goes off-camera to the right.]

149:25:36 Young: Okay. Houston, you want to Reset (the UV camera)?

149:25:38 England: Roger. Reset and I have new setting.

149:25:44 Young: Okay. Let me watch the wheels go around. (Pause)

149:25:53 Young: Reset; and it did work. It's working.

149:25:57 England: Okay.

149:25:58 Young: And what are the new settings, Houston?

149:26:02 England: Azimuth, 326.

149:26:05 Young: 326.

149:26:06 England: And elevation, 16. (Pause)

149:26:18 Young: Okay. (Pause)

[Fendell finds Charlie, who is visible beyond the LMP seat
as he packs the rock box at the MESA.]

[Fendell pans up to look at the Ascent Stage. In Houston,
Flight tells EVA (the person responsible for keeping track of the timeline
and planned activities) that he thinks John has parked on the wrong
heading.]

149:26:56 Duke: You want an unbagged rock in the rock box, Tony? I
don't think you do.

[Charlie is saying that there is an unbagged rock in SCB-2
and wants to know if it should go into the rock box along with the bagged
samples and core tubes.]

149:27:03 Young: Okay, a 326, and what's the elevation, Houston.

149:27:06 England: Sixteen.

149:27:10 Young: Sixteen. (Long Pause)

[Charlie has probably put the unbagged rock aside on the
MESA and now takes the empty SCB to the Rover. He tosses it in his foot
pan and reaches under his seat to get another SCB. He pauses a moment,
possibly to look at his checklist and then bangs the bag against the seat
frame, possibly in an effort to get the top open.]

149:27:37 England: Okay. Charlie, yeah, you can put unbagged rocks
in the SRC.

149:27:43 Duke: Okay. (Long Pause)

[Charlie stands the SCB upright in his footpan, gets a core
tube out of his seat pan and inserts it into a stowage sleeve in the SCB.
During the following conversation, he reaches across the Rover and gets
something - possibly a sample - out of John's seat pan.]

149:28:06 Young: Got the hammer, Charlie?

149:28:08 Duke: It's in the thing here.

149:28:10 Young: Okay, fine.

149:28:11 Duke: The seat. (Pause)

149:28:18 Young: I think this bag here has got so little in it we
can...

149:28:20 Duke: Let's empty it into the SRC; some more will go in
the SRC.

149:28:23 Young: Well, okay. But this has got those two
whatchacallems there.

149:28:27 Duke: What you mean?

149:28:29 Young: (Garbled)

149:28:29 Duke: Oh, those - Yeah; okay. They can't go in the
SRC.

149:28:32 Young: Where do they go, in the ETB?

[Charlie takes the SCB to the MESA. Its top is now open. Fendell pans right and finds John at the CDR seat. He is working with an SCB that appears to have little, if anything, in it.]

149:28:36 Duke: Ah, no; in a rock bag somewhere. Why don't you put them back here in mine, John. It's back on the Rover here.

149:28:44 Young: Okay.

149:28:46 Duke: Back on the Rover. (Pause)

[John turns the SCB upside down, takes the bottom in his left hand and shakes it to get something out.]

149:28:59 Young: There you go. (Long Pause)

[John takes the SCB to the back of the Rover. He then
appears to attach the SCB to the tool carrier. Fendell pans left to watch
Charlie at the MESA.]

149:29:26 Duke: We're packing up the rock box, Tony.

149:29:29 England: Okay, good.

[Charlie has removed the Beta-cloth protector, which was covering the seals on the
rock box, and discards it to his left.]

149:29:30 Duke: Got the rocks in it. The liner's coming off.

[Charlie removes the Teflon
"spacer" from the rock box and tosses it off-camera to his left.]

149:29:37 Duke: And I put the other core tubes in a...Tell you in a
minute. (Pause)

[Charlie closes the top of the rock box and latches
it.]

149:29:49 Young: (Still attaching the SCB to the back of the Rover)
Beautiful, they just fit right in the top.

149:29:52 Duke: Good. What's the number on that one, John?

149:29:56 Young: That's SCB-2. No. Yeah, 1.

149:30:02 Duke: Okay, and John's crystalline
rock and the two other core tubes go in (SCB) number 3, Tony.

149:30:14 England: Okay.

[John goes to the LMP seat. He doesn't appear to be carrying anything so, whatever it was he shook out of the SCB, it probably wasn't a sample. John is probably looking in the seat pans to make sure they haven't overlooked any samples.]

149:30:17 Duke: John, have you got...Where'd those two core tubes go that you had?

149:30:20 Young: I put them in here. Four and forty-five are in your seat (lost under Charlie).

149:30:23 Duke: Oh, okay, then I got them already.

149:30:25 Young: Okay.

[Charlie goes off-camera to the right, probably carrying the
SCB so he can pack the film magazines in it as per LMP-22. John goes around the back of the Rover and joins Charlie off-camera to the right.]

149:31:22 Duke: I know. I think I can stuff them in this other bag
(meaning SCB-3) over here, John.

149:31:26 Young: Okay.

[Most of the rocks they collected went into John's SCB.]

[Fendell starts a counter-clockwise pan. In Houston, Flight is having
a discussion with Experiments, who are pointing out that, at this point,
SCB-3 is supposed to be empty and under the LMP seat for use during EVA-3. At 149:30:02, they heard Charlie say that he was putting some full core tubes and John's crystalline rock in SCB-3 and, by inference, that he was planning to take it up to the cabin. Tony joins the SCB discussion in Houston.]

149:31:27 Young: I'll take SCB-1 and put it by the footpad,
Charlie.

149:31:32 Duke: Okay. (Pause) Yeah, I can stuff them (meaning the samples that were in Charlie's SCB) in here (meaning SCB-3).

149:31:36 Young: Let me get these core tube caps out of here. Out
of (SCB-)1 and put them under the seat pan. (Pause) Okay. (Pause) I'll
put them on the HTC, how would that be?

149:31:58 Young: That's fine, that cap (dispenser) is empty.
(Pause)

149:32:04 England: Okay, Charlie, you called out that you put two
core tubes and John's crystalline rocks in SCB-3; that should have some
empty core tubes and core caps in it (that are planned for use during
EVA-3). Could you straighten that out?

149:32:18 Duke: No, we...It had two core tubes empty that we used.
We used the bag, Tony, that's true...

149:32:40 England: There's no problem as long as you took those core tubes and core caps out.

149:32:46 Duke: We don't...(Stops to listen)

149:32:47 Duke: Well, we got the core caps out, but we didn't get the core tubes out and I don't know whether...We must have used them!

[Part way through his pan, Fendell raised his aim and continued turning the TV until he found the high-gain antenna on the front of the Rover. He then raised his aim some more and is now looking at Earth.]

149:32:57 Young: This here has a couple of core caps in it too, Charlie; in (SCB) number 1.

149:33:00 Duke: How about core tubes?

149:33:02 Young: (Garbled, possibly "Glad they asked"); a couple of core tubes in number 1.

[Fendell has zoomed in on Earth. At maximum zoom, the apparent diameter of Earth - which is two degrees - is equivalent to about one third of the vertical height of the TV field-of view. About one quarter of the Moon-facing hemisphere is sunlit.]

[Fendell has stopped his pan and has zoomed in on some footprints, Rover tracks, and rocks northeast of the Rover. After giving the people in the Backroom a few seconds to get a picture off the TV monitor, he pulls back on the zoom and pans to the right again.]

[They have probably dropped the glass ball. Bailey and Ulrich, in "Apollo 16 Voice Transcript Pertaining to the geology of the landing site" identify this sample as 65016, while, in the caption to Figure 45 of the Professional Paper, sample 65016 is identified as a Station 5 sample, probably the one John examined at 145:20:52. Readers should note that Bailey and Ulrich don't really make a clear decision about 65016; specifically, they identify 65016 as BOTH the 145:20:52 specimen and the glass ball the crew is collecting here at the LM. However, in the Station
5 TV coverage, we can clearly see John drop the 145:20:52 specimen and,
therefore, I am inclined to believe that 65016 is the glass ball they have
just dropped.]

149:35:56 Young: Aw rats!

149:35:58 Duke: Those things just bounce out of your hand. It's like...(Long Pause) Okay, I got magazine Lima; the 500's going back under the seat. Might as well drop it in the dirt, as clean as that seat is. Okay, got to get the camera over there. (Long Pause)

[Fendell finds John at the back of the Rover. John turns and heads for the ladder with SCB-1. Charlie is off-camera, and is probably loading John's camera into the ETB.]

149:36:45 Duke: Okay.

149:36:46 Young: Okay, Houston. Okay, SCB number 1 is sitting over
there on the foot strut, Charlie.

[Charlie comes into view at the LMP seat. He grabs the DAC
and rotates it on its staff so he can get at the film magazine for
removal.]

149:36:52 Duke: Okay; the mag's coming off the 16, (and I'm
orienting the DAC so the) battery's into the Sun...

[Charlie is still working at the LMP seat, perhaps
re-organizing the gear in the seat pan.]

149:37:22 England: (Passing on a request from Fendell) Okay, point the (TV) camera lens directly away from the Sun and down first, and then you can turn the LCRU off. Also, when you get back to the LRV, we'd like the LRV readouts. We didn't catch those. (Pause) And we'll need LCRU blankets all the way over.

149:37:39 Young: Okay, point the camera away from the Sun. (Stops to listen) They're all the way open now.

[We get a good view of the dust coating falling off the battery cover as John opens it. Don McMillan has provided an animation ( 0.8 Mb ) of the battery covers on his Virtual Rover being opened.]

149:38:18 Duke: You know what you sounded like then?

149:38:20 Young: What?

149:38:21 Duke: That old nursery rhyme. "This is the church, this is the steeple, open the door, and here are the people." (Scanning LMP-22) Okay, two padded bags, we're just going to leave. One set maps, we got; one mag from DAC; one mag. Okay, it's all loaded. Padded bags are staying under the seat, Houston.

149:38:37 England: Okay. (Pause)

149:38:42 Duke: Okay, and the ETB's coming over and I'm going to hook it on the (lanyard hook)...(Pause)

149:38:55 Young: And the batteries do need dusting.

[In John's shadow, we see him unstow the big
dustbrush. A detail from training photo KSC-71PC-777 shows the dustbrush stowed on the front of the training Rover.]

149:38:59 England: All right, we saw it come off those covers (at 149:38:15).

149:39:00 Duke: Do you want me to do that, John? I can reach better.

149:39:02 Young: I can get it. (Hearing Tony) Those LCRUs, yeah.

[John now dusts the battery covers.]

149:39:10 Duke: Man, we got a lot of rocks.

149:39:12 England: Good show.

149:39:14 Young: Only way to fly, Charlie.

149:39:15 England: The name of the game.

[John now dusts the LCRU mirrors in the foreground of the TV
picture.]

[Charlie's next transmission indicates that he is scanning his
checklist and noticed the item "Large Rocks (LRV) to
SCB".]

149:39:16 Duke: And we don't have Big Muley yet. (To Tony) Don't let us forget to get Big Muley here.

149:39:22 England: Oh, we wouldn't do that.

[Big Muley ( 175k ) is the 11.7 kg breccia they collected at the rim of Plum Crater. It has been sitting in the
plus-Z (ladder) footpad since Charlie put it there at the end of EVA-1.]

149:39:23 Duke: That beauty's coming in, if I have to sleep with it. (Pause) Okay, (as per LMP-23) I'm going to get Pallet 2 out; (pause) with enough food for the Trojan army.

149:39:43 Young: (Laughing) Charlie.

[John is now dusting just off-camera to the left.]

[Pallet 2 contains food and replacement batteries and LiOH canisters for the PLSSs. It is stowed in the MESA. According to the Final LM Stowage List, Apollo 16 carried a 10.5 pound (4.8 kg) 'food assembly' in the LM ascent stage and two 4.6 pound (2.1 kg) 'food assemblies' in the descent stage. One of the latter is in Pallet 2 and the other was in Pallet 1, which they took up to the cabin at the end of EVA-1. See, also, the discussion following 153:48:13.]

149:39:47 Duke: Agh! Oh, look at that, John. It just comes right out of there; and I had so much trouble (pause) in training. (Pause) Okay, "pallet 2, MESA, (ECS) LiOH can, MESA". Hmmm. (Pause) Do we have that, Tony?

[Charlie is looking for the replacement LiOH canister for the LM ECS system but doesn't see it. What he is having trouble remembering is that, at Houston's request, he took it out of the MESA at 125:26:47 at the end of EVA-1 and he and John took it up to the cabin. The change in procedure was caused by the landing delay.]

149:40:20 Duke: Yeah, that went up yesterday, so...Okay, then we
won't worry about that.

[Jones - "I've just been thinking about how relaxed and
unhurried all of this is."]

[Duke - "Yeah. By now, we were getting real familiar. You know,
real confident in the suits; and we were real confident with our
procedures. And, you know, we'd really worked a routine to work together;
and it just made you comfortable."]

[Jones - "Had that pallet given you trouble all the way through
training or..."]

[Duke - "Well, when I say pallet, you know, there was an old
training article that everybody used; and it was just old, and the stuff
was in racks and everything got out of align and it would get twisted a
little bit and you couldn't get it out and it'd stick and they did whatever
they did to it - graphited it. So it was frustrating. So, when it worked
here, it was always a miracle. 'Eureka! It worked!' 'Cause we had a lot
of trouble with the old training gear."]

149:40:28 Young: Okay, Houston, as you know, the one I have the
most trouble getting (dusted) is that mirror in the middle which I
understand is just the Nav system anyway. But I got it as best I could and
it's a lot cleaner than it was.

149:40:38 England: Okay, understand.

[John goes around the front side of the Rover so he can dust
from the right side of the vehicle.]

149:40:39 Young: Both of the Rover battery mirrors are as good as
they were when we got here.

149:40:45 England: Okay.

149:40:46 Duke: This one needs dusting, John.

149:40:47 Young: I know. I ain't dusted it yet.

149:40:48 Duke: Okay. I'm going over and kick off on the strut
here. (Pause)

[Charlie is going over to the ladder and is kicking his
boots against the ladder strut to knock some of the dirt off his
legs.]

149:41:00 Duke: Boy, that shadow is getting short!

149:41:02 Young: Maybe we landed later than we thought, Charlie.

[As shown in Figure 2.3-1 in the Lunar Surface Procedures
volume, they had planned to end EVA-2 at about 131 hours, when the Sun's
elevation was about 28 degrees. Because of the landing delay and the
decision to have a rest period before doing EVA-1, the Sun's elevation is
currently about 38 degrees. The LM shadow is only about 9 meters long.
When they landed, the Sun's elevation was about 15 degrees and the shadow
was about 26 meters long.]

149:43:19 Young: Certainly does. I put it in there a minute ago.
(Long Pause) No. (Pause)

149:43:38 Duke: Got it!

149:43:39 Young: I figured it would really be good (laughing)
because we'd keep the top closed.

149:43:44 Duke: And the way to close these things is bang on them.
There you go. Okay, that's good. Okay, I'm gonna just go up and take one
of them up, John, and then I was going to come back down. I'm not going
inside.

149:43:56 Young: Okay.

[Charlie is assuring John that he won't go in the cabin
until John's had a chance to brush him off.]

149:43:59 Duke: You want to take the brush?

149:44:00 Young: Yeah.

149:44:03 Duke: Here you go.

149:44:06 Young: Charlie, why don't you let me get them. Let me
clean you off, you go up in there, hook on, and let me just carry those
things upstairs.

149:44:12 Duke: Hook on to what?

149:44:14 Young: Hook on to the upstairs.

[John may have been thinking that Charlie would be hooking
up to the LM ECS or that he was going to hook up the clothesline-type LEC
that was flown on the missions prior to Apollo 16. In either case, he is
mistaken and this may be yet another sign of fatigue.]

149:44:17 Duke: I'm not going to hook on to anything up there. I'm
going to stand there and wait on you.

149:44:20 Young: That's what I mean. Go on up there and let me just
bring them all up.

149:44:25 Duke: You've got four things to bring up.

149:44:27 Young: No problem.

149:44:28 Duke: But you want to...Whatever you want to do. (Pause)
Okay, let me pull my visor down. (Long Pause) I can't believe it. Tony,
do we look as dirty to y'all as we do to each other?

149:45:08 Young: Well, we've got two (extra) hours, and I got the
feeling we're going to stand up tonight (laughing) cleaning each other off.
(Long Pause)

[Just prior to the second rest period, at 128:18:33, Tony told
John and Charlie that they would get two extra hours - one Command Module
orbit - added to the period from EVA-2 wake-up to the start of the
post-EVA-2 rest period.]

[John brings up the first of the SCBs and tries to put it
into the cabin far enough that Charlie can bend down and grab
it.]

149:57:30 Duke: I got it.

149:57:31 Young: Got it?

149:57:32 Duke: Yeah.

149:57:33 Young: Okay.

149:57:34 Duke: Yeah. How do you read, Houston?

149:57:37 England: We're copying you, Charlie.

149:57:42 Duke: Okay. I just heard a little squeal back there (and)
I was curious.

149:57:48 England: All right. We had a (site) hand-off.

149:57:53 Young: Ah so. (Pause)

[It is currently about 23:52 hours, April 22, 1972,
Universal (Greenwich) Time. The Moon is about to set at the Madrid tracking station and, for the next eight hours or so, communications will
come through the Goldstone station in California.]

149:58:01 Duke: These bags come open...The SCBs come open when you
don't want them to and you can't get them open when you want them to.

149:58:11 England: Okay. We'll call that Charlie's Law.

149:58:16 Duke: Yeah. (Pause)

[This is a reference to Murphy's Law - "If any thing
can go wrong, it will." and its many corollaries. My favorite is
O'Toole's Rule: "Murphy was an optimist."]

[John has probably gone down the ladder to get the second SCB and is
now passing it in.]
